The utility model has the advantages of simple structure and reasonable design, measurement accuracy is high, performance detection is reliable.
Description
Technical field
The utility model relates to automobile sensor field, particularly relates to a kind of CMPS Camshaft Position Sensor.
Background technology
CMPS Camshaft Position Sensor is a kind of sensor for detecting vehicle cam shaft position, and hall sensor technology is the most ripe instantly, makes sensor chip collection and output signal to ECU by Hall effect, thus realizes automobile smooth ignition.But the CMPS Camshaft Position Sensor output accuracy of existing conventional design is not high, after often needing engine cam to rotate 3 ~ 10 circles in advance, the signal of sensor ability stable output, visible Measurement reliability and precision are not high.
Utility model content
The utility model provides a kind of CMPS Camshaft Position Sensor, solves prior art cam shaft position sensor Measurement reliability and the not high technical matters of precision.
The purpose of this utility model is achieved through the following technical solutions:
A kind of CMPS Camshaft Position Sensor, comprise: Hall chip 1, ring-shaped magnet 2, housing 3, circuit board 4, wire 5, wherein, described housing 3 is provided with support, support is fixed with Hall chip 1, ring-shaped magnet 2, circuit board 4 and wire 5, described wire 5 and described Hall chip 1 are welded on the upper/lower terminal of described circuit board 4 respectively, and described ring-shaped magnet 2 is located at above described Hall chip 1, and described ring-shaped magnet 2 hollow space is just to described Hall chip 1.
Technique effect of the present utility model is:
Structure is simple, reasonable in design, measuring accuracy is high, detection perform is reliable.The utility model makes than the portfire of conventional engines that vehicle exhaust discharge quantity reduces, fuel oil is more abundant.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, also can obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in further detail the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, for a kind of CMPS Camshaft Position Sensor, comprise: Hall chip 1, ring-shaped magnet 2, housing 3, circuit board 4, wire 5, wherein, described housing 3 is provided with support, support is fixed with Hall chip 1, ring-shaped magnet 2, circuit board 4 and wire 5, and described wire 5 and described Hall chip 1 are welded on the upper/lower terminal of described circuit board 4 respectively, described ring-shaped magnet 2 is located at above described Hall chip 1, and described ring-shaped magnet 2 hollow space is just to described Hall chip 1.
Wherein, described Hall chip 1 is positioned at above gear ring.
The utility model also comprises mounting hole 6, is provided with trip bolt in described mounting hole 6.The utility model can be fixed on cam box by trip bolt.
Ring-shaped magnet 2 is placed in the top of Hall chip by the utility model, and by ring-shaped magnet 2 hollow space just to described Hall chip 1, working sensor magnetic field is made to derive zero field region, the real-time signal that the generation of zero field region makes sensor collect is more accurate effectively, the precision exported is also higher, therefore, the utility model sensor can export the stabilization signal that ECU needs while engine start, shortens the duration of ignition widely.
Technique effect of the present utility model is:
Structure is simple, reasonable in design, measuring accuracy is high, detection perform is reliable.The utility model makes than the portfire of conventional engines that vehicle exhaust discharge quantity reduces, fuel oil is more abundant.
Be understandable that, the system architecture shown in figure does not form the restriction to system, can comprise the equipment more more or less than diagram, or combine some equipment, or different deployed with devices.
Above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
